Not really a nutrition thing, but I've dealth with a lot of back issues.

I bulged a disc squatting. Not even heavy. Form slipped for a split second. Pow, shooting pain, life has never been the same.

I dealt with it and stayed out of the gym for almost a year. Chiropractor did nothing. Physical therapy... THAT did it. Stretch, stretch, stretch. Loosen the lower back, hamstrings, and hips with some simple stretches and implement some daily ab exercises. Strength will return slowly, but it will return.
